摘要： A compact high-torque mechanical speed changer, which offers a very wide range of output speeds in different angular directions through selections from sets of fully-interchangeable planet and sun gear combinations, and in which one predetermined counterweighting unit provides matching for the eccentricities associated with all the planet gears of such sets, comprises two sets of planet and sun gear combinations each having a one-tooth difference in numbers of effective teeth, the two externally-toothed planet gears being coupled together angularly and being mounted for eccentric rotation relative to a supporting input crankshaft, while the associated internally-toothed sun gears are respectively fixed with the changer housing and with an output member rotatable collinearly with the input shaft. Planet-gear teeth or lobes are of epitrochoid curvature, and all of the planet gears of such sets are of the same diameter; concomitantly, the companion sun gears, which are preferably of the type involving discrete roller-pin teeth rather than continuous-curvature teeth, are of the same diameter and only the number of such rollers varies from set to set. In other dimensional respects the gear sets are substantially identical and can therefore be interchanged to effect different ratios and directional senses of input to output speeds. A counterweight offsets the input-shaft and planet-gear eccentricities, and serves any selected planet gears from such sets. The changer housing and interior mountings for gear combinations accommodate assembly of the sets, as desired, to yield various speeds and directions of output.

摘要： In an autoloader having a tape deck for reading and recording on magnetic tape cassettes, such as are used for computer data back-up, a removable magazine for holding a number of cassettes in which a locking and ejection mechanism locks the magazine in position in the autoloader and permits its automatic or manual release and ejection from the tape deck. The magazine has no protrusions on its side, top or bottom surfaces that would interfere with easy insertion into and removal from the autoloader and which would, also, interfere with simple and easy storage of the magazines in a back-up facility. Any size magazine can be inserted in the autoloader without modification of the autoloader. A first latch member engages a receptive space in the magazine when it is partially inserted and stores ejection energy. A second latch member locks the magazine in position when it is fully inserted. The magazine may be released from the autoloader automatically under electronic control or manually by physically releasing the second latch. The stored energy then ejects the magazine a sufficient distance to enable an operator to remove it by hand.

摘要： A reversible drive system is provided that is particularly adaptable to low-power drives in which precision mechanical control must be obtained with the lowest possible cost and the highest reliability. The drive is described as incorporated in a lead screw drive in which a control nut reciprocates between two fixed positions. At the end of the movement in one direction, the control nut strikes a fixed abutment that stops the motion thereby increasing the load on the drive motor and causing an increase in the current drawn by the motor. This increase in current is utilized to disconnect the power source from the motor. In such systems, in particular where there is a large reduction in the speed between the motor and the driven object, as with the use of a lead screw drive arrangement, it is desirable to store energy at the end of each stroke that is available to decrease the starting torque required to reverse the direction of motion. To provide additional starting torque, the motor coupling includes a lost-motion coupling by which no significant load is placed on the motor until the output shaft of the motor, or an element driven by the motor, has moved through some fraction of a revolution. For most applications a lost-motion arrangement equivalent to about one hundred eighty degrees of motion is practical.
摘要翻译：提供了可逆驱动系统，其特别适用于低功率驱动，其中必须以最低的可能成本和最高的可靠性获得精确的机械控制。驱动器被描述为并入螺杆驱动器中，其中控制螺母在两个固定位置之间往复运动。在一个方向的运动结束时，控制螺母撞击一个停止运动的固定支座，从而增加驱动电机的负载，并引起电机拉动的电流增加。利用这种电流增加来将电源与电动机断开连接。在这样的系统中，特别是在电动机和被驱动物体之间的速度大幅度降低的情况下，与使用丝杠驱动装置一样，希望在每个行程末端存储可用于减小反转运动方向所需的起动转矩。为了提供额外的起动转矩，电动机联轴器包括一个空转联轴器，在电动机的输出轴或由电动机驱动的元件已经移动了一小部分转动之前，不会对电动机施加显着的负载。对于大多数应用而言，相当于大约一百八十度运动的失速运动是可行的。

摘要： A storage library with a simplified operating mechanism for computer back-up data cartridges. The cartridge is placed in a tray in an opening in a sealed storage chamber and transported into and removed from a multi-tier storage carrousel by a robotic arm. When a tape is to be retrieved, the arm moves the stored cartridge either to a module or directly to the window tray. A simple transmission operating the carrousel permits any cartridge to be moved to the storage-retrieval station in no more than two revolutions of the multi-carrousel central drive shaft. The use of a carrousel reduces the distance the arm must travel and decreases the time for storage or retrieval of a cartridge. Only two of seven axes have incremental positioning controls: the vertical lift and the carrousel rotation. All other axes have fixed travel distances. A cartridge gripper is compliant, readily adaptable to different cartridge configurations, and materially reduces the need for precision positioning.
摘要翻译：具有简化的计算机备份数据盒操作机制的存储库。将盒放置在密封储存室中的开口中的托盘中，并通过机器人手臂运输到多层存储转盘中并从其移除。当要取出磁带时，手臂将存储的墨盒移动到模块或直接到窗口托盘。操作转盘的简单变速器允许在多转盘中心驱动轴不超过两转的情况下将任何筒移动到存储检索站。旋转木马的使用减少了臂必须行进的距离，并减少了存放或取出墨盒的时间。七个轴中只有两个轴具有增量定位控制：垂直升降和转盘旋转。所有其他轴都具有固定的行程距离。墨盒夹持器符合标准，易于适应不同的墨盒配置，并大大降低了对精密定位的需求。

摘要： A Positive Fluid Displacement Device (PFDD) with single piece double-ended pistons connected to a crankpin for circular motion. Pistons are nested together to maintain all pistons in the same plane perpendicular to the axis of the crankshaft. Cylinders are driven in a reciprocating fashion by the pistons and are held loosely in a cylinder carriage along its axis with radial sealing engagement therebetween. Pliable members mount port plates within a housing such that there is no direct contact therebetween or with a two-layer manifold. A flat surface of the port plate is urged against the cylinder head by a pliable member which exerts a force on the center of the port plate. Grooves in the first layer of the manifold are sealed by the second layer to form fluid passageways. The cylinder head is guided in housing grooves with a pliable member. A sealing lip is integral with a piston head.

摘要： A method for grinding epitrochoidal, hypotrochoidal, and circular bearing races in one set-up without moving the part and insuring near perfect concentricity between all of the bearing races. A machine blank is mounted on an upper rotary table that is in turn mounted on a lower rotary table. The upper table is driven both by the lower table and by an independent servomotor. The net speed of the upper table is the difference between the two driving speeds of the tables. The axis of rotation of the upper table can be offset from the axis of rotation of the lower table. The tables are rotated in opposite directions while a grinding wheel is moved laterally into contact with the surface of a rough-machined part to form the trochoidal surface. The characteristics are determined by the offset, the diameter of any rollers that are to be positioned between the trochoidal surfaces in the speed change device, and the relative speeds of the two tables. After the trochoidal surface or surfaces are completed, the lower table is stopped in its home position and the upper table is driven to grind the circular bearing race or races. Three independently-driven grinding spindles are laterally adjustable with respect to the tables.

摘要： A fluid pump has two pairs of rectangular oppositely-disposed pistons. The pistons of each pair travel simultaneously in opposite directions at the same speed and over the same distance. Valving is provided by a reciprocating port plate, in face-to-face relation to the piston, driven in a circular path from two spaced crankpins and which in turn drives the associated piston. The sliding movement of the port plate controls the alignment of inlet and exhaust ports in the piston and port plate. The excursion or "throw" of the pistons can be varied from zero to maximum. A crankpin throw-adjusting mechanism simultaneously adjusts the throw of each crankpin, some in one direction, some in the opposite, so that all chambers are automatically adjusted for varying, but always identical, displacements. Self-lubricated seals between the piston and chamber walls are spring loaded, by an elastomerically sealed structure having non-linear deflection-to-force characteristics.

摘要： A number of data storage cassettes are held in a removeable magazine that forms part of a tape drive by which the magnetic tapes are recorded or played. The magazine holds two parallel vertically-displaced decks of cassettes that are moved under positive driving force along a rectangular pathway formed by the two decks. From a pick-up position in the magazine, a cassette is automatically extracted by a robotic arm and placed in the tape platform for reading or writing by a conventional tape drive mechanism. When the use of the cassette is finished and it is ejected by the tape drive, a sensor activates the robotic arm to return the cassette to the pick-up position. Each deck has one unoccupied cassette space. If during the sequence of operations, the cassettes on the lower deck are moved by the width of one cassette in one direction, the cassettes on the upper deck are moved the same distance in the opposite direction. This movement results in a vacant position at the end of the upper deck farthest away from the pick-up position. The cassette in the pick-up position is either removed and loaded into the tape deck or the cycle is continued. Movement of the cassette is produced by reciprocating drivers along the sides of the magazines. The cassettes are moved in only one direction by the reciprocating drivers and are locked to prevent movement in the opposite direction. Motions of the cassette handling mechanisms are limited by mechanical stops that trigger an electronic circuit to interrupt the driving power eliminating the need for sensitive position switches. Slip clutches prevent mechanical damage from the mechanical stops. The removable magazine does not include any electric motor drives and is automatically disengaged from the cassette driving mechanism by its removal, thus permitting economical use of multiple magazines.
摘要翻译：许多数据存储盒被保持在可移除的盒中，该盒形成磁带驱动器的一部分，磁带被记录或播放。该杂志具有沿着由两个甲板形成的矩形路径在正向驱动力下移动的两个平行的垂直移位的盒式盘。从杂志的拾取位置，盒式磁带由机器手臂自动提取并放置在磁带平台中，以便通过传统的磁带驱动机构进行读取或写入。当盒式磁带的使用完成并被磁带驱动器弹出时，传感器激活机器人臂将磁带带返回到拾取位置。每个甲板上都有一个空闲的磁带空间。如果在操作顺序期间，下甲板上的盒子沿一个方向移动一个盒子的宽度，上甲板上的盒子沿相反方向移动相同的距离。这种运动导致在上甲板的最远离拾取位置的端部处的空置位置。拾取位置的磁带盒要么被取出，要么被装载到磁带机上，要么循环继续。磁带盒的移动是通过沿着杂志侧面的往复驱动器产生的。盒通过往复驱动器在一个方向上移动并被锁定以防止在相反方向上的移动。磁带盒处理机构的动作受机械停止的限制，触发电子电路中断驱动功率，从而消除了敏感位置开关的需要。滑动离合器可防止机械停止的机械损坏。可移动的杂志不包括任何电动机驱动器，并且通过其移除自动地从盒驱动机构脱离，从而允许经济地使用多个箱。

摘要： A speed reduction mechanism having an orbital drive system. A first crank arm drives the orbital system and a second crank arm, offset by 180 degrees, carries a counterweight for counter balancing the off center forces produced by the orbital system.To minimize inertia, the counterweight is symmetrically shaped about its axis and is mounted for free rotation about the second crank arm. Such a counterweight may have a smaller degree of eccentricity and a correspondingly greater mass than a conventional counterweight, but because the inertia is a function of the square of the eccentricity of the counterweight, the inertia may be significantly less.
